SPECIFICATION forming part of Letters Patent No. 302,130, dated July 15, 1884.

Application filed November 22, 1883. (No model.)

To aZZ whom it may concewti Be itknown that I, J ULIUs THEODOR HASSE, a subject of the King of Saxony, and a resident of Dresden, in the Kingdom of Saxony, haveinvcnted certain new and useful Improve ments in Gas Generating and Consuming Furnaces, of which the following is aspecification. This invention relates to furnaces or ovens heated by gas, particularly to retort-furnaces for the generation of illuminating and heating An object of my improvementis to provide suitable means for the reception of the retorts; another, to secure an equal distribution and cfficiency of the heating-gases in the furnace or oven, so that no dead spaces will exist. A further object is to secure a preliminary heating of the air used for combustion, and also to secure a thorough mingling of the air and combustible gas for operating-theoven. I at-' tainthese objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows in its left half a transverse section of a retort-oven in the plane A B, Fig. 3,

plane 0 D, Fig.3. Fig. 2 is a vertical transverse section through the generator in the plane E F, Fig. 3. Fig. 3 is a vertical longitudinal section in the plane G H, Fig. 1. Fig. 0 4 is avertical longitudinal sectionin the plane J K, Fig. 1. Fig. 5 is a'horizontal section in plane L M, Fig. 1. Fig. 6 is a horizontal sec tion in the planeN 0, Fig. 1. Fig. 7 is a horizontal section in the plane P Q, Fig. 1. Fig.

1. Fig. 9 is a vertical sectidn in the plane T U g- 3. Similar letters indicate corresponding parts. Among other things, the invention relates to 40 the manner of placing the retorts. As seen in Fig.1, the retorts are walled in by stones or supports, so that each retort rests by itself, and not so that one retort is weighed'down by another one. The retorts a rest upon the stones 5 b, the retorts 0 upon the stones d, and the retorts 6 upon the stones f. The retorts are not braced against the vault of the oven, but rest freely in the oven, and can consequently easily resting between the retorts a and '0, as also between the retorts c ande, do not serve for the support of the retorts-but are onlyfor the formation of drafts in the oven. The wedges g serve for securing the-retorts in a fixed position. Between the walls of the retorts and the ceiling of the oven-vault is a space. The placing of the supporting-stones, as also their form, secures an equal distribution, and consequently an equal efficiency of the heating-gases in the oven, so that there will not be any dead-spaces. The generator for the formation of theheating-gases lies in front of the oven in a lower position. The carbon'icoxide gases generated in the generator pass through a channel. 1), leading from the generator to .the retort-oven, and can thus be exactly regulated. The channel p is so constructed that a constant layer of burning material or fuel can be maintained in i the generator. The slits or openingsh allow the entrance of the gases into the oven, and

through the openingsi is led in the air, which has first been warmed in the channels through which it is led. The openings 72 and h are so constructed thatathorough mixing of gas and air must take place. Thereby the combus- 7 tion is not only the most thorough, but the heating-gases also are burned at the proper place, and are so thoroughly utilized that they only pass into the escapechannel q with the low temperature of 400 centigrade. The generator itself is not affected by the fire and is almost indestructible. The walls of the generator are provided with air-channels k, in which the primary air is heated before being led under the grate of the generator. In con- 8 sequence of this arrangement the disagreeable radiating heat of the generator is almost wholly removed, these channels is surrounding the generator not only at the sides, but also at thefront. The fire-chamber has a grate 0 which lies about twentyfive centimeters (about ten inches) above the sole of the generator, and below which are conduits a, for the primary air to be led in, and which has been first warmed, and a, for the steam or water. vapor to 5 be led in, as also a vessel, 8, of cast-iron, which receives the water of condensation. The air 7 follow the movements of the oven. The stones and steam conduits are advantageously protected against choking up by a roof-like covering of sheet metal. The heating material is by all these arrangements thoroughly burned, only ashes and slag remaining on the grate, which can be pulled out by a hook. The stones Zform a rest or support for the coke in the generator, and hinder the coke falling down during the removal of the slag and ash. These stones lalso hinder the air and water vapor entering underneath the grate from gliding up along the walls of the generator, and compel them to pass through the fuel. In the oven under the retorts and at each side of the oven lies asystem of channels intended to heat the secondary air prior to its being burned in the oven, and also to lead off the spent heating-gases. The secondary air is led to the oven through the channels m. Through the channels at the spent heating-gases are led off. The air-channelsm lie between the gas-channels n, and the heat radiating from the latter thus heats the air in the channels m to a high temperature. The air enters into the lowermost of the channels at through openings in the wall of the furnace, as indicated in Fig. 8, and the successive tiers or layers of channels m are caused to communicate by vertical or other suitable perforations, Fig. 7, which are so placed that the direction of the flow of air is different in any one channel from its direction in the channel at immediately above orbelow. By means of partitions between the channels m, lying on the same level, Fig. 8, the air in such channels is also caused to flow alternately backward and forward. The construction of the channels mat various levels may vary from that just described in connection with Fig. 8, such modified construction being shown, for example, in Fig. 6. The spent gases pass from the retortvault into the upper layer of channels n, Fig. 5, and thence back and forth through the successively lower channels, n, until they pass into the escape-channel q, Fig. 4. The successive tiers of channels a communicate by vertical or other suitable perforations or channels, as seen in Fig. 7, in the same manner as the successive tier's or layers of channels m. The channels at and n are formed by stones shaped for this purpose, and are covered with a double layer of plates. In the oven at each side of the gas-generator lies the automatic steam-generator 0, which is fed by water which can be caused to continually flow into it by any suitable device. The steam generated is led into the conduits under the grate of the generator by suitable pipes or other means. The steam-generator may be provided with a water-glass and safety-valve, as also with an overflow-pipe. The generation of steam is caused by the heat of the oven. The generator is hermetically closed in front of the grate by an air-tight closing-door.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a retort-oven and with a gas-generator, of a channel, 1;, leading from the generator to the oven, primary airchannels It at thesides and in front of the generator, and openings h, for the' entrance of gases, and openings 1, for the entrance of air, whereby the gases and air are mingled and consumed in the retort-chamber in the immediate presence of the retorts, substantially as set forth.

2. The combination, with a retort-oven and with a gas-generator, of a cast-iron furnace plate or vessel, 8, projecting stones Z, air-conduits a, and steam-conduits it, placed beneath the grate of the generator, and a boiler, 0,placed in said oven, adapted to be heated by the spent gases, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
